Cationisation of cotton and nylon 6 fabrics has been done using Solfix
E, Tino fix Eco, Acramine berfix
K and cetyl trimethyl ammonium bromide to impart cationic sites on fabric
surface for improving their substantivity to acid dyes. Pre-cationisation of cotton and nylon 6 fabrics improves the depth of the colour as well as fastness
properties. In all
the cases, the overall colour fastness of cationic cotton dyed with acid dyes
is found to be comparable to the colour fastness of the nylon 6 dyed with same
acid dyes.
